What is Modic-2 degenerative endplate changes?
Modic changes, a common observation in MR imaging, are signal intensity changes in vertebral body marrow, adjacent to the endplates of degenerative discs.Michael T. Modic, MD, professor of radiology and neurology at Case Western in Cleveland, wrote about these changes in the journal Radiology in 1988, and his name has been associated with these changes ever since.Modic changes take 3 main forms:Type I· Decreased signal on T1, and increased signal on T2.· Represents marrow edema.· Associated with an acute process.· Histological examination shows disruption and fissuring of the endplate and vascularized fibrous tissues within the adjacent marrowType II - the most common type· Increased signal on T1, and isointense or slightly hyperintense signal on T2.· Represents fatty degeneration of subchondral marrow.· Associated with a chronic process.· Histological examination shows endplate disruption with yellow marrow replacement in the adjacent vertebral body.Type I changes convert to Type II changes with time, while Type II changes seem to remain stable.Type III· Decreased signal on both T1 and T2.· Correlate with extensive bony sclerosis on plain radiographs.· Histological examination shows dense woven bone; hence, no marrow to produce MRI signal.MODIC CHANGES on MRIT1T2SignificanceTYPE 1¯­EdemaTYPE II­® (or slight­)Fatty DegenerationTYPE III¯¯Bony Sclerosis

What is L5-S1 mild reactive endplate and marrow edema?
Marrow edema and mild endplate findings could be inflammatory spondyloarthropathy. This could indicate anything from ankylosing spondylitis (AS)and back pain associated with psoriatic arthritis or inflammatory bowel disease (IBD).
What is red marrow hyperplasia and heterogeneous marrow pattern narrowing replacing lesion to suggest these changes reflect a marrow infiltrative process of the spine. multiple myeloma?
What is red marrow hyperplasia
What is acromioclavicular joint degenerative change with marrow edema involving clavicle at the joint mean?
I think acromioclavicula joint degenerative change with marrow edema involving clavicle of the joint means ---the AC joint shows signs of artritis with swelling/inflammation of the Clavicle joint itself. The acromio + clavicula are actually two joints that connect for rotating (gliding) function of the shoulder. This is my best guest and I'm no medical professional.
Most bone contain yellow what?
In adults, most bones contain yellow marrow (primarily fat).In children this is often red marrow (to generate blood cells), but changes to yellow marrow as we age.
Why is bone marrow primarily red in infants?
Infants grow relatively fast and need quite a lot of red blood cells, which are only produced in red bone marrow. As the infants grow older, much of the red bone marrow is gradually replaced by yellow bone marrow containing a special kind of fat that gives it its yellowish color. If the body needs more red blood cells than the remaining red marrow is capable of producing, some of the yellow marrow changes to red marrow.
